classnum {pgirmess} | R Documentation |
Gives an index vector of the class category of each value of a numerical vector
classnum(x, breaks = "Sturges")
x |
a vector of values for which the indices are desired |
breaks |
one of:
|
The default for 'breaks' is '"Sturges"': see 'nclass.Sturges'. Other names for which algorithms are supplied are '"Scott"' and '"FD"' for '"Friedman-Diaconis"' (with corresponding functions 'nclass.scott' and 'nclass.FD'). Case is ignored and partial matching is used. Breaks and labels are stored as attributes.
A vector of the same length as x, with the index of the class which each value of x belongs to
